To all whom t may concern Be it known that i, CHARLES E. Brno, av

citizen of the United States, and resident of Chicago, in the county of Cook and State The prime object of this invention broadlyA stated is to utilize vthe ticking or other textile fabriccover for the springsv of a mattress as a means for sustaining the springs in their upright operative position vfrom .contact with each other, and to have the end coils 'of adjacent springs so connected with the cover that the springs are held in an upright position against substantial lateral movement, the one independently of the other. Y

More specifically stated the object of-my invention is to provide a means by which the fabric of the ticking or other textile fabric inclosing the springsvmay -be projected between and prevent the contact ofv the end coils of adjacent springs, and in such a manner that metallic clips may be passed through the fabric'free from contact with the springs for securingv the fabric against accidental detachment therefronn.

A further object of vmy invention is to `provide a' means by which that portion of the textile coverk projected between the springsmay be permanently distended and thereby prevented from receding therefrom when locked by a metallic clip,l the legs of which are projected through the surface of the cover free from contact with the springs.

A. further object ofl my invention is a mattress provided with upright coiled springs connected in such a manner that the weight of the body -thereon is distributed als uniformly as may be consistent with its resiliency, and which, however much or violently it may be compressed will be noiseless.

.With these ends in view, my invention finds embodiment in certain features of novelty in the construction, combination andarrangeme'nt of parts by which the said objects and certain other objects are attained, allv as hereinafter fully described with reference to the accompanying drawings, and more particularly pointed out inv the claims.

ln said drawing: Figure 1 is a. detail top plan view of,y a mattress or cushion seat, las may be in which my invention finds' em-y bodiment. Fig. 2 is an enlarged vertical section therethrough taken on the line 2-2 of Fig'. 1. Fig.v 3 is a similar view of 'the upper portion of the mattress taken on the line 3-8 of Fig. 1. 4 is a detail section ,showingv the application of my inven- -tion to a stu'ed or .box mattress, ,and Fig. 5

is a detailfsection showing a 'modification in the form and location of the fastening clip.

.Similar characters of reference indicate the same parts in the several figures of the drawings.

Springs 5y are preferably ofl the hour glass type, but may be of other helical form, and of which there are a number, corresponding with the size of the mattress when arranged as they are with their end coils adjacent each other, which springs are provided with a surrounding cover. 6 of tick or other textile fabric, the .dimensions of the cover being such that portions thereof between the springs may be crimped to provide folds 7v projecting downwardly between the adjacent end coils of the springs.

rlhe springs are secured to the cover, and' thereby maintained in their' upright position by means of clips 8, the legs of which pass through the cover free from contact with the neck of the coils of the springs,

and by their compression against the folds .7, prevent the neck of the fold from spreading apart when the `cover'is depressed by the weight of the occupant, and the clips from striking contact l against the springs coniined therein. rlihe cover 6 is stretched .tight fromedge to edge, both longitudisprings by the clips 8, so that the folds 7 are not stretched thereby. As the best means for securely locking the folds 7 of the cover to the springs, these folds are distended by means of fibrous ropes 9 passed therethrough, the diameters of which are such that they cannot pass between the adjacent end coils. The ropes 9 instead of being in short pieces for the purposes above described, preferably extend the full length of the mattress so that secured as they are by the clips to the fabric of the cover against endwise movement, they operate to distribute practically over the surface of the mattress the force produced by the occupant from a violent'impact of his body against any one of the springs.

While it is true that the folded projections of lthe cover between the springs produce pockets l0 thereinit should be observed that these pockets are so small as compared with the surface of the coverdirectly` above and' over the ends of the springs, that substantially the greater portion of the surface of the cover is normally level, partly filled as are the pockets by the ropes passing therethrough. -A

For some purposes no supplemental covers need be employed, but for thepurposes of a box or stuffed mattress or seat, an outer cover l1 is employed for a stufhng l2, as indicated in F ig. 4, which may be of hair, felt or other materials commonly employed for stuffing mattresses.

In Fig. 5 is shown a modification' in the form of the fastening clip, the head` of which 13, is extended in a straight line against and parallel withthe surface of the cver, with its legs lil-14: projecting at a right anglel to the head provided with inwardly projected prongs forced through the fabric of the coverinto the rope.

In conclusion it should be observed that my invention f provides a construction of spring mattress which when once assembled requires no re-adjustment of the tension of'- the springs for wear and which is not only strong and Vdurable, ybut noiseless and pro- Vducible at aV maximum cheapness both in cost of material and labor required for its construction. v j

Having described my invention, what I claim and desire to secure by Letters Patent 1. A mattress comprising in combination a series of upright helical springs, a woven fabric cover therefor, folds depressed therefrom projecting between and isolating the end coils of adjacent springs from contact with each other, and means spaced from contact with the end coils of adjacent springs, connecting the surface of the Cover with the projecting fold, and maintaining the springs against material lateral move: ment the one independent of the other.

2. A device for the purposes described comprising in combination a series of upright helical springs, the end coils of which are adjacent each other, a ticking or other woven fabric overlying the ends of said springs, folds in said cover projecting between the end coils of adjacent springs, means for distending said folds, and a fastening means projecting through the. cover and around the distended fold therein.

3. A device for the purposedescribed comprising a series of convolute springs arranged with their end coils adjacent each other, a textile fabric covering therefory provided with folds projecting between the end coils of said springs, a rope for distending'said folds and a fastening means for securing the ropes to the fold and preventing a lateral movement of the springs, the one independently of the other.

(4L. A device for lthe purposes described comprising in combination a series of convolute springs arranged with their end coils adjacent each other, a cover extending over the outer ends of said springs provided with folds projecting between the adjacent end coils thereof, fibrous ropes distending said folds, extending from one edge of the cover to the other, and clips projecting 4through the surface of. the cover and securing the ropesv against movement independently of the movement of the springs.

5. A device for the purpose described comprising in combination a series'of upright hour glass springs arranged with the end 100 coils of the springs adjacent each other, a fabric extending across and coveringv the ends of said springs, folds therein projecting between the adjacent end coils of said springs, fibrous ropes crossing each other 105 and extending from edge to edge of said cover, and passing through and distending the projected foldsthereof, clip plates passe ing through the cover and clenched against the surface of the distended folds spaced 110 from contact with the springs and maintainin the springs from a lateral movement independently of each other.

In witness whereof, I have hereunto set my hand and affixed my seal, this 23rd day 115 of April, A. D. 1915.
